These statistics suggest that the Read Cache is marginally effective (35% hit rate), although much faster, compared to the 24GB Readyboost. The Write Cache is highly effective.

What would be helpful for analysis purposes is a FancyCache datalogger that would record the Performance Monitor for post-analysis. With datalogging, we could quantify write flushes, write buffer performance, read hits, etc. This is what “real” software testers do, no?
